What is the London plane?
London aircraft is a hybrid plane that has evolved from a random crossing of the American Sycamore and the oriental plane. London aircraft have tall and majestic, with some trees reaching 98 feet (30 m), have greenish gray trunks, twisted branches and shiny green leaves. They are popular urban residents and can be seen dotting the urban landscape in London and southern England, as well as in many parts of Oregon in the US.
In addition to its attractive appearance, the popularity of the London flat tree in urban areas is caused by its persistent and durable nature. It is a tree that can prosper in almost any kind of soil, growth in limited spaces and endure the effects of pollution. The bark of the London aircraft tends to turn away in sections and reveal the inner white bark; This regular exfoliation prevents any long -term damage to pollution. It changes its color to brown in the autumn. While the London plane casts its leaves completely in winter, it provides shadowResidents of towns in the summer. It also offers shelter for the range of wild birds.
In May, yellowish male flowers and reddish female flowers on separate long stems on the same tree grow. The fruit then produced usually occurs in pairs and is round with bristle hair around the world; It is known that these hairs cause allergic reactions. Fruit seeds are generally sterile and new trees are planted cuts.
As with most trees, London aircraft are doing well with regular fertilization. They have a rapid growth speed and may require frequent pruning to keep them at safe, mastered heights and from the way of electric or telephone poles. The trees are generally very durable and long -term, with some existing specimens known to be over 200 years. However, it is necessary to protect against the excursions of pests such as American plum borer and KTomato bug Sycamore, and against diseases such as anthracnosa, leaves, mold and cankers.
The wood of the London aircraft is known as lace wood. This is in relation to the relatively soft, lace appearance of its grain. It is very hard and durable and is used to make furniture, floors, mowing blocks and other objects.
